Hi, I have created a conda environment including a python and keras-gpu installation using the instructions on this blog post . However, when I try to set up that in KNIME->Preferences->Python and once I browse the .bat file it says “testing python installation…” and after a few moments my system goes on the Blue Screen of Death and restarts. I tried multiple different conda environments with different versions of python and keras, but it happens every time. I used to use KNIME 3.7.1 on Windows 10, but then I downgraded my KNIME installation to 3.6.2 to see if it has to do with the KNIME version, yet it happened again. My system has four NVIDIA TITAN GPUs and an Intel Core i9 CPU with 64GB of RAM. Any advice would be appreciated. Thanks

Thanks everyone for your helps. The issue is now resolved. Here is what I did: 1- instead of creating a conda environment (which led to blue screen crash), I set the base anaconda python installation (version 3.6.6) in the KNIME python integration preferences. 2- After installing python via Anaconda 3.5.1, I used the following commands to update packages: conda update conda conda update anaconda 3- Following the updates I installed keras-gpu version 2.1.6 which automatically installs Tensorflow-gpu 1.12.0, CUDA 9.0.1, and cuDNN 7.3.1 using the following command: conda install keras-gpu=2.1.6 4- Apparently cuDNN 7.3.1 is not compatible with the installed versions of CUDA and Tensorflow-gpu however. So the last thing you need to do is to downgrade the cuDNN version to 7.1.4 using the following command: conda install cudnn=7.1.4 That’s it. I successfully ran the KNIME deep learning example “Generate_Fairy_Tales” after that on GPU.

There was a discussion about phyton here. One idea could be to try not using the bat file.

Can you use the Python environment at all? Have you tried running a few commands there?
